搭建方式可參考：
http://www.reibang.com/p/faf038923093
參上以上簡書內(nèi)容搭建即可醉蚁，但是存在如下四個(gè)問題需要補(bǔ)充：
- 需要bin目錄替換萧吠，至 https://github.com/steveloughran/winutils下載對(duì)于版本的bin答捕，并添加到hadoop中即可。
- nodemanger無法啟動(dòng)
- 啟動(dòng)nodemanager存在路徑無法打開的問題
- wordcount無法運(yùn)行
解決方案：
針對(duì)2,3,4三個(gè)問題，首先yarn-site.xml的內(nèi)容需要修改為
<?xml version="1.0"?>

- 每個(gè)節(jié)點(diǎn)的可用最大內(nèi)存需要注意分配的大一些病曾，此處分配為4096，之前分配為2048斤斧，若分配的小了勺美，會(huì)存在map 0 reduce 0 情況
